Cisco ASR 1000 Series Route Processor
How Cisco ASR1000-RP Alarm Monitoring Works
The Cisco ASR1000-RP1 or Cisco ASR1000-RP2 faceplate displays the CRIT, MAJ, and MIN alarm
indicator LEDs. An external element can be connected to a power supply using the DB-25 alarm
connector on the power supply. The external element is a DC light bulb for a visual alarm and a bell for
an audible alarm.
If an alarm illuminates the CRIT, MIN, or MAJ LED on the Cisco ASR 1000 Series Route Processor
(RP) faceplate, and a visual or audible alarm is wired, the alarm also activates an alarm relay in the power
supply DB-25 connector (on the Cisco ASR 1006 Router and Cisco ASR 1004 Router). The bell rings
or the light bulb flashes and alerts site personnel that a router alarm condition exists.
Shielded cables must be used to connect to the DB-25 alarm connector on both the AC and DC power
Note
supplies, in order to comply with the FCC/EN55022/CISPR22 Class A emissions requirements.
The alarm signals sent to this DB-25 connector are identical in function to those sent to the system LEDs
on the Cisco ASR1000-RP1 and Cisco ASR1000-RP2. Each alarm consists of three contact pins that are
switched when an alarm becomes active which causes a corresponding contact closure between the
DB-25 connector pins. As a result a critical, major, or minor alarm condition detected in the router can
trigger a simultaneous fault indication in some of the following ways:
•
•
An external audible alarm can be reset by clearing the condition that caused the alarm or by pressing the
Audible Cutoff (ACO) button on the Cisco ASR1000-RP1 and RP2. An audible alarm can be sounded
to immediately alert you of an alarm condition in the router. An audible alarm generated by the system
continues to sound until you either clear the alarm condition itself or press the ACO button to silence the
alarm. Pressing this button does not resolve the alarm condition.

System alarm LEDs—The three system alarm LEDs on the Cisco ASR1000-RP1 and RP2 faceplate
constitute the standard method of alarm notification in the router. These LEDs indicate router status
at all times, but you must directly observe these LEDs to become aware of a router alarm condition
See
Table 2-6
for LED descriptions.
External alarm monitoring facility—By equipping your router with a telco-style external alarm
monitoring facility, you can provide a more physical indication of router status. A visual alarm,
however, can be reset only by resolving the problem that caused the alarm condition.
To clear an audible alarm, do one of the following:
–
Press the Audible Cut Off button on the route processor faceplate (see
–
Enter the clear facility-alarm command.
To clear a visual alarm, you must resolve the alarm condition. The clear facility-alarm command
does not clear an alarm LED on the RP faceplate or turn off the DC light bulb. For example, if a
critical alarm LED is illuminated because an active SPA was removed without a graceful
deactivation of the SPA, the only way to resolve that alarm is to replace the SPA.
